[boost] [Property Tree] registry parser bug

boost::property_tree::read_registry does not handle registry keys that contain periods correctly.

Example: When I run the following code

     boost::property_tree::ptree pt;
     string key = "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Drivers32";
     boost::property_tree::read_registry(HKEY_LOCAL_MACHINE, key, pt);
     boost::property_tree::write_xml("Drivers32.xml", pt);

I get the output below.
But there is no registry key "msacm".
There are registry keys "msacm.imaadpcm", "msacm.msadpcm" etc.
